MACHINE FOR OPERATING UPON THE HEELS OF BOOTS AND SHOES.

Application led September 5, 1914.

ings, is a specification, like reference characters on the drawingsindicating like parts in Vthe several figures.

This invention relates to machines for operating upon the heels of bootsand shoes and is herein illustrated as embodied in a machine forscouring the corners of the heel at the junction of the breast With theedge.

`It'sometimes happens that at the junction of the corners of the heelwith the shank of the sole there are left, after the heel breastingoperation, more or less pronounced bunches or burs of untrimmedmaterial; and hitherto this material has commonly been removed by aknife in the hand of the operator. It is very desirable, however, thatthe finished corners shallbe smooth since other- Wise they detractgreatly from the appearance of the shoe.

One object of the present invention is to remove these burs in asatisfactory manner.

To this end one feature of the invention comprises a scouring tool,means for rotating' said tool in one direction when one corner of theheel is being scoured and means for rotating it in the oppositedirection when the other corner is being scoured, the direction ofrotation in each case being such that each corner is scoured from theoutside toward the center of the shoe. In this Way the liability toproduce ragged and unsightly edges is avoided.

During the heel breasting operation it sometimes happens, particularlywhen high heels are being operated upon, that the edge of the breastingknife trembles so that the corners of the heel are Vgiven more or lesswavy contours; or itmay happenthat the breasting knife twists slightlyso that the corners of the heel are not properly located with respect tothe medial line of the sole. In the one case it is desirable tostraighten the corners, and in the other to bring them to a common planeproperly located With respect to the shoe.

To this end, as Well asin order to facili- Specicaton of Letters Patent.

Serial No. 860,392.

tate the proper removal of the burs referred Patented N ov. 2f, 193i@ toabove, another feat-ure of the invention comprises a scouring tool, twoWork rests located symmetrically `with respect to said tool and meansfor moving a selected Work rest to present a corner of the heel to saidtool. By presenting first one corner of the heel and then the other tothe tool by means of Work rests located symmetrically With respect tosaid tools, the corners may be brought into the proper common plane atthe same time they are straightened.

These and other features of the invention including certain details ofconstruction and combinations of parts Will be described in connectionWith an illustrative machine and pointed out in the appended claims.eferring now to the accompanying draw- 1ngs,-I `igure l is a perspectivevieiv partly in section of a machine in which the present invention isembodied; Fig. 2 is a rear elevation of the parts shown in F ig. l; Fig.3 is a vieiv of the cam for operating the belt Shifters, F ig. l is aplan of a portion of the machine showing in dotted lines a shoe inpositions to have the corners of the heel scoured, and Fig. 5 is aperspective showing more particularly the mechanism for re versing thedirection of rotation of the scouringA tool.

The illustrative machine comprises a shaft l mounted in suitablebearings in the machine frame, on one end of which is fastened by anysuitable means a tool herein shoivn as a conical scouring Wheel 3, thebase or larger end of which is situated at the front of the machine asshown in Fig. l. @n the conical surface of this wheel is mounted thescouring material 5, and in operation the shoe is moved so as to bringthe corner of the heel into contact with the Wheel so as to remove anybur or bunch of untrimmed inaterial. The shaft l also carries tivo loosepulleys 7, 9 and a driving pulley ll, which latter is fixed to the shaftl. The loose pulley 7 is connected to the main driving shaft 8 by acrossed belt 13 and the pulley 9 by an open belt I5, and means areprovided for shifting one or other of the said belts on to the drivingpulley 1l so that the shaft l may be driven in one or the otherdirection as desired. rIhese means comprise tivo belt Shifters 17, 19which are pivoted at 2l, 23 one on either side of the frame of the ma- Ychine.

one of the belt shifters 17, 19 will be moved by its cam groove so as toshift its belt on to the driving pulley 11 and so drive the shaft 1 andscouring wheel 3 in one direction, while when the other treadle isdepressed the other belt shifter will be moved by its cam groove sothatits belt will be shifted on to the driving pulley and the wheel 3rotated in the other direction. lt will be seen that as one belt shiftershifts its belt from its loose pulley to the driving pulley 11 the otherbelt shifter will shift its belt from the driving pulley to its loosepulley should its belt be driving the shaft 1 at the time the other beltshifter is operated. When the treadles are in their inoperative positionthe two belts are situated on their loose pulleys as shown in F ig. 1`

The machine is provided with two work Y supports 41, 43, one of which isused when one corner of the heel is to be scoured and the other when theother corner is to be scoured, and means are also provided for movingupwardly each one of the work supports so as to bring the corner of theheel into engagement with the roll B. Means are also provided wherebythe work rest appropriate for the particular corner only raised to bringthat corner into engagement with the'wheel 3 when the said wheel isrotating in a direction such that the said corner will be scoured in adirection from the outside of the heeltoward the center of thev shoe. inorder to carry this into veffect Vthere are mounted on the cam shaft Y35 two arms 45 47 the arms 45 beinO' ada 3ted when the cam shaft 35 isrotated in one direction as just described, to engage and raise the worksupport 41; and the arm 47, when the cam shaft is rotated in the otherdirection, to engage Vand raise the work support 43.

Each work support comprises a plate havprojecting therefrom a ledge 49against which the corner of the heel opposite to the one being operatedupon is adapted to bear during the scouring operation. Each work supportis provided with a downwardly proj'ecting stem 51 which is adapted tofit into the bore 53 of a thimble 55 and is held adjustably in positiontherein by meansof a set screw 59. The thimble is adapted to slide in abearing in the machine frame and is held normally in its loweredposition by means of a spring 61 situated inside the thimble, one end ofwhich bears against the bottom of the thimble and the other end againsta pin 63, which passes through the bearing in which the thimble slidesand also through a slot in the said thimble. The pin 63 also serves tolimit the downward movement of the work support under the action of thesaid spring.

Between the work supports 41, 43 is sit-V uated a guard 65 in the formof a circular metal plate which extends acrossthe base of the wheel andis provided to Vprotect the shank of the shoe from the said wheel-f Theguard 65 is providedwith a downwardly eX- 1 tending portion 67 Vwhich issecured by a belt, as shown in Fig. 1, to the machine frame so as toholdvthe guard in position.

In order to scour the corners ofthe heel of a boot or shoe the shoe ispositioned'upon one of the work supports, as for example.

43, which is appropriate to the particular corner to be treated, withthat corner uppermost and with the apex of the angle'at the junction ofthe heel breast and the shank against the edge of the circular guardplate G5, the sole of the shoe from the heel to the toe projectingacross said guard (see Fig. 4). The treadle which is appropriate to thework support 43 is then depressed, with the result that the cam shaft 35is turned in a counter-clockwise direction viewing the machine from thefront. VThis will move thercam 33 so that the cam groove 29 will,through the caln roller 25 on the belt shifter 17, move this beltshifter and cause it to shift its belt 13 on to the pulley 11. rEheVbelt 13 is driven ina direction such that when viewing the machine fromthe front thewheel 3 will be rotated in a clockwise direction. Thescouring wheel is thus first started up and thereafter by the continuedactuation of the treadle the armV 47 will engage and lift the worksupport 43 so that the corner of the heel will be moved up into contactwith the wheel 3. |The operation having been completed on this corner,the machine is stopped and theshoe is placed on the work support 41 in apositionreorresponding to that just described, so as to bring theunscoured corner into position in readiness to be scoured. When :theshoe is in position on the rest41the treadle which Y is appropriate tothis restis depressed and the other corner scoured in the Ymanner pre-Vviously described. Y

It will be understood that by having the means for lifting the worksupport and the mechanism for reversing the .direction of rotation ofthe shaft 1 operatively connected together the corner to be operatedupon'will be brought into engagement with the scouring` wheel when thewheel is Vrotating in a direction such that it will scour the saidcorner from the outside of the heel toward the center of the shoe.

It will be noted from an inspection of Fig. 4 that the work rests 41, 43are located one on each side of the frusto-conical wheel 3 and aresymmetrically arranged with respect to said wheel, the plates 49 beingparallel respectively to diametrically opposite elements of the'frusto-conical wheel. With this construction and arrangement of partsthe corners of the heels of all shoes which have been operated upon willlie in a plane which bears a iiXed relation to the medial line of thesole.

Although the invention has been set forth in connection with aparticular machine it should be understood that the invention is notlimited in the scope of its application to the particular machine shownand described.
